Picked this up on the $30 rebate deal, $62.37 shipped from Newbiz.com
Used CBABE to flash it to 840/2125 @1.3v.
Worked on overclocking the core mostly, can get 850 @ 1.327 but it runs cooler at 1.3v, 59C under full load with a VF900. That's crammed in an Ultra Microfly.
Thought the GDDR3 was stellar hitting 2125MHz, figured it was near the limit so I left it.
After a few days got motivated to push the memory clocks. Boy, what a big surprise!!!!!
I am now at 2400MHz on the ram, and I don't think there is anyway GDDR3 will hit that speed
at stock voltage. I have some nice copper ramsinks on it, but it has to be GDDR4.
Verified the clock speeds with ATItray tools and running 3Dmark06 (breaking 12K now).
Has anyone heard of any manufacturer putting GDDR4 on a 3850?
I figure it is more likely they had lots of 3870's unsold and just flashed it to a 3850, repackaged and sent it out the door.
Gonna try higher later, some people managed to get their 3870's to 2600MHz or more on the memory.
